Abstract
The present disclosure is directed to systems and methods of maintaining source device to sink device synchronization in systems in which the source device enters a Panel Self-Refresh (PSR/PSR2) mode and the sink device enables adaptive synchronization with the source device. To maintain synchronization, in some instances the source device and the sink device may maintain synchronization contemporaneous with at least a portion of the PSR/PSR2 operating mode. To maintain synchronization, in some instances, a high-bandwidth communications link may be maintained between the source device and the sink device. In some instances, synchronization between the source device and the sink device may be interrupted upon the source device entering the PSR/PSR2 operating mode and may be re-established upon the source device exiting the PSR/PSR2 operating mode.
